I only have an exact place of birth for my GG Granfather Edmund. He was born in 1833 in Whitegate, County Galway, Ireland. (The county borders were moved and Whitegate is now located in County Clare). Edmund married Mary Mulhall.
Mary Joyce b. County Galway m. Frederick Doepel
Ann Joyce dob unknown m. John Thomas
Catherine Joyce b. abt. 1839 m. Hans Peter Seiersen
Patrick Joyce b. abt. 1839 m. Adelaide Toovey
Jane Joyce b. 1845 m. Neils Peter Johansen
These dates come from "Joyce - Descendants of Edmund and Catherine Joyce in Australia 1855 to 1975"
Hope this is of some help,
